  • Patent number: 11974582
    Abstract: Mollusc processing apparatus and related methods are disclosed. The molluscs have a first shell, a second shell and an adductor muscle attached to the shells. Multiple holders hold a respective mollusc by the first shell of the mollusc. A conveyor is coupled to the holders to move the molluscs between processing stations. One processing station is a shell cut station to cut an opening into the shells of each respective mollusc. Another processing station is a muscle cut station to cut the adductor muscle from the second shell through the opening in the shells of each mollusc. A further processing station is a shell detach station to detach the second shell from the first shell of each respective mollusc.

  • Patent number: 9840376
    Abstract: The present disclosure relates to apparatus for carrying articles such as fruit for sorting, and in particular though not exclusively to apparatus for singulating the articles. There is provided a singulation apparatus for an article carrying system, the apparatus comprising a flume adapted to receive a plurality of articles at a first end; a fluid inlet associated with the first end and arranged in use to direct a fluid flow to carry the received articles along the flume to a second end; wherein a parameter of the fluid flow is controlled in order to singulate the received articles along the flume. A method for singulation is also disclosed.

  • Patent number: 9033772
    Abstract: A method for producing frozen oysters on the half shell, which comprises the steps of freezing live oysters in their shells, so that the oysters hinges will break open; subjecting the frozen oysters to a water treatment to promote disengagement of the oysters' flesh from one thin shell; and percussing the water treated oysters, so that at least one shell will be knocked off.

  • Publication number: 20140120813
    Abstract: A method for shucking bi-valve shellfish, especially clams, includes imparting a wide array of infrared energy from at least one infrared heater from above to a first shell of the bi-valve shellfish sufficient to detach an adductor muscle from the first shell. The bi-valve shellfish are inverted to expose a second shell. Infrared energy is imparted again from above to a second shell of the bi-valve shellfish sufficient to release a shellfish meat from between the first and shell and the second shell. A system for carrying out this method includes a tank for washing the shellfish, a dryer, the infrared heaters, a device for inverting the shellfish, a tank for quenching the shellfish, and a conveyor for transporting the shellfish under the infrared heaters.

  • Publication number: 20130149946
    Abstract: A cryogen-blanching technique involves brief exposure of an oyster shell to a cryogen. The cryo-blanching weakens the oyster's muscles that close the bivalve tightly shut, but preserves the natural condition of the bulk of the oyster meat. The weakening of the oyster's holding muscles allows shucking the oyster meat in its fresh or natural state without damage or shell fragments.

  • Patent number: 6537601
    Abstract: The invention relates to a process for eliminating pathogenic organisms and other bacteria from raw food products, such as raw shellfish, whereby the molluscan shellfish is exposed to hydrostatic pressure of relatively high value, for example between 10,000 p.s.i. to 60,000 p.s.i. for 1-15 minutes. The process is conducted at elevated temperatures, in the range of between 50 and 130 degrees Fahrenheit, leaving the raw shellfish substantially unaffected, in its desired raw state, such that the pathogenic organisms are destroyed, while sensory characteristics of the raw shellfish remain high. The same process can be used for shucking bivalve mollusks without any mechanical force, with the pressure ranging from 10,000 p.s.i. to 60,000 p.s.i. Taste of raw seafood is enhanced by adding flavor enhancing agents to the pressure vessel before application of pressure.

  • Patent number: 6086468
    Abstract: A bivalve peeling-off method and apparatus and a before-separation heating device are disclosed. The bivalve peeling-off apparatus includes a heating means 6 for heating the surface of one of shells 2A of a starting bivalve 2, so that an edible part 2a in the starting bivalve 2 is maintained in a raw state. Thus, the edible part can be efficiently separated from the shell of the starting bivalve in a state in which a quality suitable for use in raw eating is maintained.

  • Patent number: 6010397
    Abstract: A method of processing bivalve molluscs comprises filling a basket-like container (11) with the bivalve molluscs and vibrating the bivalve molluscs within the container (11), thereby inducing them to close tightly under stress and compacting them together. A lid (12) is closed to maintain the compact configuration of the bivalve molluscs, which are cooked by immersing the container into boiling seawater, before being removed and plunged into chilled water to halt the cooking process. The bivalve molluscs are then blast frozen. Because the shells of the bivalve molluscs are tightly closed and better compaction is achieved by vibrating the bivalve molluscs than by compressing them into the container (11), the shells are unable to open and the internal juices are retained within the shells throughout the cooking, chilling and freezing steps, thereby resulting in processed bivalve molluscs having greatly improved organoleptic qualities upon thawing.

  • Patent number: 5059151
    Abstract: Method and apparatus for opening a mollusk (e.g., oyster) by rapidly cooling said mollusk to a surface temperature of about -100.degree. F. followed by mechanically agitating said mollusk whereby the mollusk shell opens and at least one eye of the mollusk meat is detached from the shell. Subsequent to cooling and prior to agitating, the mollusk can be rapidly immersed in a water bath to raise the surface temperature of the mollusk to no more than about -50.degree. F. Individually quick frozen mollusk meat can be prepared rapidly either as an individual portion of meat or on the half shell.
